No it started after the coils were upgraded. It seems like a misfire, it's like it's only running on 3 cylinders or something. And it does it at idle and under all rpms it stays until I shut the car off and let it sit for a while. Then I restart it and it's gone. Sometimes it never happens till its been shut off for a while after running it, then I start it up and it has it again. There were no parts replaced right before it started happening. The last thing that was put on before the problem occurred was the catless downpipe and borla exhaust. Maybe it's a bad o2 sensor?
Yes I do. So you want me to try putting the four old coils back in and see what happens?
Ok I'll put them in and check the spark plugs while I'm at it and see what happens and then let you know. The only problem is I might have to drive it for a bit to get it to start doing the misfire since it doesn't always happen right away.
So far it seems to be running right it hasn't done the misfire again. I've been trying to drive it around to make sure it's totally gone it just has been much cooler the last couple days so I was kind of waiting to see what happens when it gets back in to the high 90s again.
